Github for image colourizationGithub repository for Colorful image colourization. The author is from Berkeley EECS, so it shouldn't be too hard to contact him if something goes wrong.

Scribbler sketch to image synthesisWebsite for a good sketch to image synthesis project. Contains a link to a Github page but the link only returns 404. Perhaps worth a try to contact the authors and asking them whether we can have their code

Auto-painter sketch to image synthesisPaper on another sketch to image synthesis project. Not found on Github (perhaps because some authors were from Samsung). Perhaps also worth contacting.
